    Abstract:
    BACKGROUND: Access to potentially life-saving screening colonoscopy is limited by the high cost of sedation. We explored the practicability of having supervised trainees perform unsedated colonoscopies. METHOD: A nursing shortage at our Veterans Administration gastroenterology training program necessitated discontinuing sedated colonoscopy. We offered the procedure without sedation to restore local access to screening colonoscopy. RESULTS: From September 2002 to June 2005, 145 of 483 patients accepted the unsedated option. The procedure was done by second-year gastroenterology (GI) fellows who had performed about 100 sedated colonoscopies in their first year of training. Cecal intubation was achieved in 81% of 138 well purged patients without obstructive lesions. Implementation obviated the need for 2 registered nurses, the escort requirement, and postprocedure activity restriction. It also eliminated sedation-related complications. CONCLUSION: This report confirms the feasibility of unsedated colonoscopy performed by supervised trainees. The unsedated option minimizes direct and indirect costs of colonoscopy. Describing unsedated screening colonoscopy to patients as a "sedation risk-free" procedure encouraged them to consider the benefits. We recommend that future studies test primary care providers' willingness to inform patients of the feasibility of this nonstandard option, and perhaps reshape the practice of colonoscopy for colorectal cancer screening.
